Inside Castel Sant’Angelo in Rome

A tour inside Castel Sant’Angelo in Rome, Italy gives visitors the clear understanding that this structure was used as a fortress, a residence, and as a prison. A passageway tall and wide enough to accommodate a horse-drawn wagon spirals from ground level to the top of Castel Sant’Angelo, allowing munitions and supplies to be brought to the upper levels. Some individual cells in the structure lent themselves to defense of Castel Sant’Angelo while other cells were more suited to penal purposes.
